Compactness and pair production in active galactic nuclei

  • 1. European Southern Observatory, Garching, West Germany

Description

Barring relativistic bulk motions, the continuum emitted by AGN's implies very compact sources. It is found that the compactness parameter k = Lc/R cannot, especially in the X-ray band, exceed a level interestingly close to the current data. In sources driven by high energy electrons, the main limitation is associated with pair production by heavily absorbed, inverse-Compton γ-rays. 13 references
